Killing Floor Sandbox Configuration

Let’s look at the global game settings, mainly sandbox. Settings are located in the KillingFloor.ini file in the [KFmod.KFGameType] section.

Enabling Sandbox

To enable sandbox, you need to set the KFGameLength=3 parameter in the killingfloor.ini file in the [KFmod.KFGameType] section.

Main Parameters

• KFGameLength — number of waves:
  • 0 — 4 waves
  • 1 — 7 waves
  • 2 — 10 waves
  • 3 — custom number of waves
• StartingCash — amount of money when entering the map (only applies when KFGameLength=3).
• MinRespawnCash — minimum amount of money when respawning after death (only applies when KFGameLength=3).
• bUseEndGameBoss — true enables Patriarch at the end of the game, false — disables.
• LobbyTimeout — time (in seconds) of delay in menu before map starts.
• bEnemyHealthBars — true enables health bars display for all players (only applies when KFGameLength=3).
• MaxZombiesOnce — maximum possible number of monsters simultaneously on the map (only applies when KFGameLength=3).
• InitialWave — wave configuration number from which the game will start (only applies when KFGameLength=3).
• FinalWave — wave configuration number at which the game will end (only applies when KFGameLength=3).
• FriendlyFireScale — amount of damage to allies (in fractions: 1.0 = 100%, 0.1 = 10%).
• WaveStartSpawnPeriod — wave spawn period (recommended value: 6.000000). Decreasing the value speeds up wave appearance.

Sandbox Parameters (KFGameLength=3)

Monster List

Each line describes a monster that can be used in the game:

MonsterClasses=(MClassName="KFChar.ZombieClot",Mid="A")

• MClassName — monster “name” (class).
• Mid — letter index (case doesn’t matter), conditional designation of monster in settings (see below).

Monster Squads

Monsters in the game spawn in groups. Each line defines the composition of one group:

MonsterSquad=4A1G

Example: 4A1G means that the group includes 4 monsters with index A and 1 with index G.

Wave Configurations

Each line sets a wave configuration:

Waves[0]=(WaveMask=196611,WaveMaxMonsters=20,WaveDuration=255,WaveDifficulty=0.000000)

• [0] — wave number. Used in InitialWave and FinalWave.
• WaveMaxMonsters — number of monsters in the wave per player.
• WaveDuration — wave duration.
• WaveDifficulty — wave difficulty modifier.
• WaveMask — numeric code that determines which squads will spawn on the wave.

How to Calculate WaveMask

Let’s say there are three groups:

MonsterSquad=4A
MonsterSquad=4A1G
MonsterSquad=2B

We need groups 2 and 3 to appear on the wave. Mentally write 1 next to each group if it should appear, and 0 if not:

0 MonsterSquad=4A
1 MonsterSquad=4A1G
1 MonsterSquad=2B

Write out the sequence of zeros and ones from bottom to top (from last to first):

110

This is a binary number. Convert it to decimal — we get 6. This value needs to be written in WaveMask for the desired wave.

Tip (Windows Calculator)

1. Switch to “Engineering”/“Scientific” mode.
2. Select Bin number system and enter 110.
3. Switch to Dec — you get 6. This is the WaveMask.
